34 * TLB0 and TLB1 Entries
36 * Out of reset, TLB1's Entry 0 maps the highest 4K for CCSRBAR.
37 * However, CCSRBAR is then relocated to CFG_CCSRBAR right after
38 * these TLB entries are established.
40 * The TLB entries for DDR are dynamically setup in spd_sdram()
41 * and use TLB1 Entries 8 through 15 as needed according to the
44 * MAS0: tlbsel, esel, nv
45 * MAS1: valid, iprot, tid, ts, tsize
46 * MAS2: epn, x0, x1, w, i, m, g, e
47 * MAS3: rpn, u0-u3, ux, sx, uw, sw, ur, sr

95 * These entries end up at TLB0 Indicies 0x10, 0x14, 0x18 and 0x1c,
